AdsGo shifts spend toward winning ad sets and campaigns across Meta and Google — without manual spreadsheet juggling.
Explore AI budget allocation →Ad budget planning starts with a clear daily goal: revenue for ecommerce, conversions for leads, clicks for traffic, or impressions for awareness. The calculator above uses US-blended industry benchmarks (updated June 2026) — most free SERP tools use the same default without a country picker. It also surfaces learning-phase minimums so you do not underfund campaigns before algorithms stabilize.
Example: 10 purchases per day at $42 CPA → about $420/day. At $12 CPM, $420/day buys roughly 35,000 impressions before frequency and placement effects.
New or reset campaigns need enough conversion volume for algorithms to learn. Underfunding this window leads to "Learning Limited" on Meta, volatile Smart Bidding on Google, or unstable delivery on TikTok.
Use these ranges as starting points — your creative, offer, and tracking setup matter more than any industry average.
| Industry | Meta CPM | Meta CPC | Google CPC | TikTok CPM | Note |
|---|---|---|---|---|---|
| Ecommerce | $10–$14 | $0.90–$1.40 | $1.80–$2.80 | $7–$11 | Retargeting lowers blended CPA |
| B2B / SaaS | $20–$30 | $3.50–$6.00 | $6–$12 | $18–$26 | Lead quality matters more than CPC |
| Local services | $8–$12 | $2.50–$4.00 | $4–$8 | $6–$10 | Call & form tracking essential |
| Education | $12–$18 | $2.00–$3.50 | $3.50–$6.00 | $9–$14 | Webinar funnels spike seasonally |
| Health & wellness | $15–$22 | $2.20–$3.50 | $4.50–$8.00 | $12–$17 | Policy limits affect delivery |
Platforms bill on daily budgets but finance teams think monthly. Use daily × 30 for simple planning. For Google Ads, monthly exposure is capped near daily × 30.4 — Google may spend up to 2× your daily budget on heavy days but averages out over the month. Add 10–20% buffer for tests and creative refreshes. If monthly spend cannot clear learning minimums, consolidate ad sets until CPA stabilizes.

For a step-by-step Google Ads workflow, read How to set Google Ads budget without wasting money. For ROAS targets after budget is set, try our ROAS calculator.
Divide daily revenue target by target ROAS to get required ad spend — e.g. $3,000 revenue at 3x ROAS needs $1,000/day. Without ROAS, estimate orders as revenue ÷ average order value, then multiply orders by your CPA. Example: $3,000 ÷ $80 AOV = 37.5 orders; at $45 CPA ≈ $1,688/day.
Start from a measurable goal: daily impressions, clicks, or conversions. Multiply conversions by your target CPA, clicks by CPC, or impressions by CPM ÷ 1,000. Then check that your monthly spend can support platform learning minimums — roughly 50 × CPA on Meta and 30 × CPA on Google over the learning window.
Meta typically needs about 50 optimization events (often purchases or leads) per ad set in a 7-day window to exit learning. A practical planning rule: budget at least 50 × your target CPA in total learning-phase spend before judging performance.
Google Smart Bidding often needs roughly 30 conversions in a 30-day window for stable optimization. Plan for about 30 × your target CPA in spend during that learning period — more if conversion volume is sparse.
Daily budget ≈ (Target daily impressions ÷ 1,000) × CPM. Example: 20,000 impressions at $12 CPM → (20,000 ÷ 1,000) × $12 = $240/day. CPM varies by industry, placement, and audience size.
Daily budget ≈ Target daily conversions × CPA. CPA = Ad spend ÷ Conversions. If you need 10 purchases per day at $45 CPA, plan for about $450/day before platform fees and creative testing overhead.
Max affordable CPC ≈ Target CPA × Conversion rate (as a decimal). If your CPA target is $50 and landing page CVR is 3%, max CPC is about $1.50. Paying above that math makes your target CPA impossible at the same conversion rate.
Google Ads averages daily budgets over a calendar month using ~30.4 days. A $100/day budget can spend up to $200 on a single heavy day, but monthly total is capped near $100 × 30.4 = $3,040 — not exactly $3,000.
TikTok campaigns typically need roughly 50 optimization events (purchases, leads, or your chosen event) in a 7-day window before delivery stabilizes. Plan for about 50 × your target CPA in learning-phase spend — similar to Meta, before judging performance.
Test each channel with enough spend to clear learning minimums, then shift toward lower CPA and higher incremental lift. TikTok often delivers lower CPMs for video-first brands; Google captures high-intent search. Use the All platforms tab for a rough ⅓ split starting point, then rebalance with your own data.
